5:  DUO Evo 
VOCAL MODELING AUTO-DOUBLER
The DUO Evo Vocal Modeling Auto-Doubler 
automatically generates a doubled vocal part 
from any existing monophonic vocal. Unlike 
conventional doublers that simply apply pitch 
and delay variation to the original part, DUO Evo 
makes use of Antares’ unique vocal modeling 
and vibrato processing technologies to create 
a doubled part that actually sounds like another 
singer. There is no easier or quicker way to create 
a realistic doubled vocal part.
Controls
VOCAL RANGE
Use this control to select the range of the track 
you will be processing. Choices include Soprano 
Voice, Alto/Tenor Voice, Bass/Baritone Voice and 
Instrument (a general setting for anything that 
isn’t actually a vocal). Matching the appropriate 
algorithm to the input results in faster and more 
accurate pitch detection.
To select the desired Vocal Range, click on the 
Vocal Range pop-up and then select the desired 
range from the pop-up list. 
NOTE: Choosing the wrong Vocal 
Range (or just forgetting to set it 
at all) can result in compromised 
performance. Pay attention.
